SPECIFICATION forming part of Letters Patent No. 626,316, dated June 6, 1899. Application filed November 1 1897. Serial No. 657,057. (No odel.)

To (all whom, it may concern:

Be it known that I, ALEXANDER WOOD, mechanic, a subject of the Queen of Great Britain, and a resident of the city of Glasgow, Scotland, have invented certain new and usefulImprovementsin Sewing-Machines forDoing Smocking, \Vaffling, or Honeycombingork, of which the following is a specification.

This invention relates to sewing-machines; and it has for its object to provide a mechanical attachment for doing smocking, waffling, or honeycombing-work such as is at present made byhand on fabrics; and in orderthat my said invention may be properly understood I have hereunto appended nine explanatory sheets of drawings which show, merely by way of example, a convenient method of car ryin g the invention into efiect or practice.

The invention has been patented in Switzerland, No. 15,571, dated October 21, 1897.

On the drawings, Figure l is aside view of an ordinary Singer zigzag-stitch machine, with the honeycombing attachment fitted thereto. A machine of the Singer type has merely been chosen by way of example. Fig. 2 is a plan view of the machine with the attachment. The head and the greater part of the arm of the sewing-machine are broken awayin order to show the attachment clearly. Fig. 8 is an inverted plan showing mechanism at the under side of the bed-plate. Fig. 4 is an opposite side view from that in Fig. 1. Fig. 5 is a section taken on the line A A, Fig. 8. Fig. 6 is a plan, Fig. 7 is a front view, and Fig. 8 is a side view, all drawn to an enlargedscale, of the bevel-gear reversing mechanism. Fig. 9 is an enlarged side view, partly sectioned, showing the clutch 74 '77 in gear; and Fig. 9 is a similar view showing the clutch out of gear. Fig. 10 is an enlarged side view of the feed-regulating device. Fig. 1O is a front View, Fig. 10 a side view, and Fig. 1O a plan, of the tooth 98. Fig. 11 is an enlarged sectional view taken on the line B B, Fig. 2, and showing the locking strip or clamp 18 in front view. Fig. 12 is a crosssection on the line C C, Fig. 11. Fig. 13 is a front view, and Fig. 14 a side view, to an enlarged scale, of the spring pawl locking depin device.

vice 19. Fig. 15 is a cross-section, to an enlarged scale, taken on the line D D, Fig. 2. Fig. 16 is an enlarged side view, and Fig. 17 an enlarged plan view, of the spring-locking- Fig. 18 is an inverted plan of the frame 14 and the mechanism connected therewith. Fig. 19 shows a modification of 21 a section, of a piece of honeycomb fabric as made by the machine. Fig. 22 is a section, to an enlarged scale, showing the plait-s and the method of tacking them together.

Referring to the drawings, whereon the same reference-numerals wherever repeated indicate the same or similar parts, 1 is the bed-plate, 2 the arm, 3 the head, 4 the needlebar, 5 the needle, 6 the tension, 8 the horizontal driving-shaft, 9 10 the fast and loose power-pulleys, 11 the drivingstrap or beltshifting fork, and 13 the shuttle mechanism, of an ordinary Singer zigzag-stitch machine. The parts for automatically stopping the sewing mechanism after the completion of the proper number of stitches at each tack, for regulating the number of stitches at each tack, for varying the tension, and for throwing the stopping mechanism out of gear are the same as the parts used on Singer machines for the same purposes. The parts consist of the stoplever 12, its spring 111, its adjusting-screw 112, the stops 110 110 on the fast pulley 9, the two-armed trip-lever 113 113, wit-h its spring 119, the stitch regulating ratchetwheel 116, the trips 117 118 on the ratchetwheel, the starting-rod 122, with its spiral spring 125, the starting-rod bracket 126, the starting crank-shaft 123, with its chain 12a connected with a treadle, (not shown,) the tension-connecting rod 128, with its spring 130, the bellcrank 7, and the tension-pin 129. As usual, the fork 11 is secured to a bracket- 127, attached to the upper end 12 of the stoplever, and the connecting-rod 128 is alsoattached to this bracket. 120 is the vertical shaft of the machine. 121 is the usual connecting-rod for the shuttle mechanism 13. 120 is the eccentric-pawl for turning the stitch-wheel 116.

This invention consists in a mechanical attachment for sewing-machines whereby what is known as honeycomb-work such as is at present done by hand can be performed on the machine.

The features of novelty constituting the invention are pointed out in the claims at the end of this specification.

Under this invention there is secured to the bed-plate l of the sewing-machine guides 15, (attached by lugs to the bed-plate,) in which slides a bar 16. The guides 15 are strengthened by a cast stay or bracket 25, secured to the bed-plate. Attached to the under side of the bar 16 is a strip 131, (see particularly Figs. 15 and 18,) having downwardly-projecting oblong pieces 132 132 attached to it. These oblong pieces pass through slots 133 133 cut in the rear part 14 of the sliding-frame 14. Secured by means of screws 134134 tothe pieces 132 132 is a lower guideplate- 135. It will thus be seen that the strip 131 and plate 135 together form guides between which the frame 14 can move to an extent permitted by the working of the pieces 132 132 in the slots 133 133. The slots and pieces are clearly indicated in dotted lines in the inverted plan Fig. 18. For the purpose of locking the frame 14 in position when moved the-springpawl locking device 19 (shown more particularly'at Figs. 13 and 14) is attached to said 7 frame. This device consists of a block 136, secured to the upper side of the sliding frame 14. Pinned in the block is a pawl137, which has a grooved face 138. (See Fig. 13.) The pawl is normally pressed forward by the spring 139, and when it is so pressed forward it projects down into and locks in either one or other of the slots 140 140" out in the plate 135". A hole 141, as indicated in dotted lines at Fig. 18 and also in fulllines at Fig. 15, is cut out of the frame 14 for the passage of the pawl. In Fig. 18 the point of the pawl 137 is shown as locked in the slot 140. The pawl is manipulated so as to raise it up out of the slot (140 or 140) with which it may for the time being be engaged by means of a tappet 142 on the rocking spindle 20. This tappet when the spindle is turned sufficiently forcesthe pawl out of engagement with the slot 140 or 140, as the case may be.

The-sliding frame 14, which is cut out longitudinally at 143, is provided with a row of teeth or nicks 144' (or their equivalent) along one edge of the cut-out part. As will be seen more particularly at Figs. 2 and 18, the cutout part has a narrow gate or passage 143.

The rocking spindle 20, which is passed through beari n g-pins 145,secured to the frame 14, has two projections or tappets 146 147 on it, which when the rocking spindle is partially turned are capable of bearingagainst the lower side of bridge-links 148 149 and raising them up in the manner indicated in dotted lines at Fig. 12. Each bridge-link is at oneend pivotally attached to a stud 150, (see Figs. 2, 1'1, and 12,) secured to a locking strip or clamp 18, and at the other end is fulcrumed in a stud 151, secured to the frame pets 146 147 of the rocking spindle.

14. The locking-strip, which has teeth or nicks 152 in.it corresponding exactly to the teeth or nicks 144 of the sliding frame, is normally pressed downward against the said frame by means of springs 22 and is capable of being raised up, along with the link=bridges 148149, by means of the projections or tap- In order to guide the locking-strip in its movements, pins 153 are secured to the frame 14, and these pins pass up through holes in the locking-strip, as shown.

The spindle 20 can be rocked by means of a handle 21. v

I Fitted also on the sliding frame is a plaiting knife or blade 17, to which a lateral movement (on the principle of the parallel-ruler) can be imparted by means of a slide 23 and links 154 155. The slide 23, which is provided with a suitable handle 24, works in guides 156 157, secured tothe frame 14. For the purpose of regulating the extent of movement of the slide a pin can be passed through any one of the holes in the slide and made to catch in a slot 45 (shown in dotted lines) in the frame 14. The left-handguide 156, Fig. 2, also servesto strengthen its end of the frame 14.

The frame 14 and slide 16 connected therei with are traversed backward and forward by means of a screwed spindle 26, whose ends pass through the bearing-blocks 27 28, secured to the bracket 25. The screwed spinclle also passes freely through a hole in an adjusting-block 29, attached by means of screws 30 to the slide 16. The adjustingblock is provided with means for looking it in any desired position on the screw 26, which I term the feed-screw. The spring locking-pin device, which is shown at Figs. 16 and 17in side and plan views to an enlarged scale, consists of a thumb-lever 33, which is fulcrumed at 159to the rib 160. This lever bears at its forward end against the under side of the head 31 of the locking-pin 31, whichlatter passes down through a hole in the block andenters that convolution of thefeed-screw 26-which is for the time being under it. The

pin 31 is pressed down by means of a spring 32, which bears at one end in a depression 32, made in the head 31, and at the other end is secured to a screw 161, screwed into the rib 160. 162 is a stop-pin to limit the downward movement of the thumb-lever 33. The pin 31 is normally held down or locked with its point in the groove of the screw by means of the spring 32, and it can be raised up out of contact with the screw or unlocked by depressing the thu mb-lever 33. When the pin is raised up out of contact with the screw, the adjusting-block 29 can be slid along the screw and the slide 16 and frame 14 be moved with it; but when the pin is locked in the groove of the screw the frame is lockedfirmly and'cannot be traversed apart from the movement of the feed-screw. The space between any two of the convolutions of the screw is equal to the free space or step made between the stitches when honeycombing.

The feed-screw 26 is driven from a countershaft 38, having a pulley 71, which is rotated by a belt 70, running on an additional pulley 70, attached to the loose pulley of the machine-shaft 8. The shaft 38 is carried in a bearing-bracket 80. When the feed'screw is rotated in one direction, it, owing to the pin 31 working in the thread of the feed-screw, traverses the frame in one direction, and when it is rotated in an opposite direction it reverses the movement of the frame.

In order to reverse the direction of rotation of the feed-screw 26, and consequently the traverse of the frame, a bevel-gear reversingmotion, such as shown at Figs. 5, 6, 7, and 8, can be used. This motion consists of an arrangement of three bevel-wheels, two, 34 35, of which are fitted to sleeves working loosely on the end of the feed-screw spindle 26, while the third, 36, is rigidly attached to the end 38 of the counter-shaft 38. Either the bevelwheel 34 or can be thrown into gear with the feed-screw 26 by means of the sliding clutch 37. This clutch consists of a metal ring 39 40, which is capable of being slid back ward and forward on the feed-screw spindle 26, so that either the tooth 41 locks in the corresponding recess 42 of the sleeve of the Wheel 35 or the tooth 43 locks in the'recess 44 of the sleeve of the wheel 34 by the action of a fork 45 whose ends catch in a groove in the clutch 37 and which is attached to a slide 46, operated by a slotted arm 47, attached to the rocking shaft 48. (See also Fig. 8.) A pin 49 on the slide 46 projects outwardly through the slot in the arm 47.

50 51 is the slide-bar upon which the slide 46 moves. The bar is fitted in snugs 52, secured to the block 27.

53 is a collar secu red to the feed-screw spindle 26 by screws 54. 55 is a guide-slot in the clutch 37, and 56 is a guide-pin fitted in the feed-screw spindle 26 and working in said slot.

The shaft 48 is rocked, so as to move the slide 46 and shift the clutch 37, by means of the device shown more particularly at Figs. 7 and 8, which is actuated by the turning of the spindle 20 of the frame 14. The device consists of a cross head or lever 57, secu red at its center to the end of the shaft 48, and the ends of this lever are connected by links 58 59 to two slides 60 61, working in a guideframe 62. At the lower end of the slide 60 is a screw 63 or pin with a flat face orpart, while at the lower end of the slide 61 a similar screw or pin 64 is fitted. 0n the rocking spindle 20 of the frame 14 two or more tappets 65 66 are fitted. The tappet 65 can be made by the turning of the spindle 20 to bear upon and depress the pin 63 and its slide 60 when the frame 14 is at the endof its back traverse, while the tappct 66 can in the same manner be made to bear upon and depress the pin 64 and its slide 61 when the frame 14 is at the end of its forward traverse. hen the pin 63 and slide 60 are depressed, the shaft 48 is rocked in one direction, and at the same time the slide 61,with its pin 64,is pulled up. When the pin 64 and slide 61 are depressed, the shaft 48 is rocked in the opposite direction, and at the same time the slide 60, with its pin 63, is pulled up. The tappets are made adjustable upon the spindle 20. The guide-frame 62 is secured to the guides 15 by screws 67.

68 is a bridge-piece for carrying the bearing-pin 69 of the rock-shaft 48.

As it is essential that the frame 14 be fed forward by the feed-screw only one step i. e., the space between two consecutive tackingstitches) at a time and then stopped during the stitching of the plaits, it is necessary that the feed-screw be stopped at every revolution (every revolution is equal to a forward feed of one step) until the stitching is done and then restarted. To effect this, there is proy'ided an automatic feed-regulating device, which is shown more particularly at Figs. 9, 9*, 10, 10, 10 and 10. This device works in conjunction with the stop-motion of the machine, v

On the shaft 38, which is made, as shown, in two parts 38 38 fitting into each other, the part 38 having a round male end 78, which enters the socketed female end 79 of the part 38", is fitted a clutch 74 77. The box part 7 7 of the clutch is fitted rigidly on the end 79 of the part 38 of the shaft, while the sliding part or clutch-piece 74 is fitted loosely on the part 38 of the shaft and has a coil-spring 73, which tends to press its pin into engagement with the hole 76, made in the box part 77. On the part 38 is a collar 81, having a hole 81, through which the pin 75 passes. The clutch-piece 74 has a grooved cam 82 in conjunction with it. Working in the groove of the cam is a pin 83, Fig. 2, attached to one end of a lever 84, (see also Fig. 10,) whose other end has a tailpiece 87.

The clutelrpiece 74 has a recess 88, with which a spring locking-bolt 89, Fig. 1'0, in the block 86 can engage. The bolt has a guidepin 99, which works in a slot 91, cut in the block 86.

The clutch-piece 74 is automatically moved into gear with the clutch-box 77 by the action of the spring, and it is moved out of gear once in each revolution of the shaft 38, and also of the feed-screw 26, by the action of the pin 83 of the lever 84, working in the grooveof the cam 82.- In order that the clutch may only be allowed to enter into gear at the proper times, the regulator (shown at Figs. 1 and 2) is provided. This regulator, which acts in conjunction with the stopmotion, consists of a lever 92, fulcrumed to the bed-plate at 93 and connected bya bar 94 with alatcral pin 96 on the stop-motion lever 12. I

97 is a spring bearing against the tooth 98, which is pivoted at 194 in the end j aw 99 of the lever. This tooth has a pointed face formed by the two bevels 100 101. (See Figs. 10, 10,

and 10?.) The tooth also tapers away toward ICC IIO

the rear, as shown at 103, Figs. 10 and 10.. Fig. 10 shows a front View of-the end of the lever 92, while Fig. 10 is a side View looking toward the left hand of Fig. 10 and showing the pointed end of the tooth,and Fig. 10 is a plan of the tooth. The pointed end of the tooth is at certain times capable of bearing against and depressing a pin 105, fitted .in a spring-bolt 106, (see Fig. 10,) which works in a hole in the block 86. The pin 105 moves vertically in a slot in the block. The dotted lines at 107 represent the spring of the bolt. The head 108 of the bolt is cut away, as shown at Fig. 2.

109 is a catch pivoted at 109 and provided with a projection 109 which is capable of catching on and holding down the pin 105.

To do honeycombing-work with the attachment, the fabric is first passed through the gate 143 and into the slot 143 of the sliding frame. One end of the fabric, as indicated by the heavy dotted line at Fig. 15, is passed between the frame 14 and the bed-plate 1 of the machine, while the other end, if it is long enough, lies on top of the knife 17. The rocking spindle 20 is now turned by the handle 21, so as to raise up by means of the tappets 146 147 the locking-strip 18 into the po-, sition shown in full lines at Figs. -11 and 15. The knife 17 is now moved laterally, so as to force the fabric between the locking-strip18 and teeth 144 of the frame 14 (in the manner shown at Fig. 15) in order to form a plait by pushing the handle 24 to the left, Fig. 2. The locking-strip 18 is now allowed to descend or close under the action of the springsv 22, so as to grasp the fabric by turning back the handle 21 to its original position, and

thereafter the knife 17 is withdrawn by merely pulling toward the right, Fig. 2, the slidehandle 24. The now platted fabric remains in place, being held securely by the spring locking-strip18, which'is closed upon it. The first plait being now made in the fabric, it is necessary to sew the first tacking-stitch, and in order to do this the treadle is depressed and the crank-shaft 123 and starting-rod 1.22 actuated, soas to force the stop-lever12 into the position shown at Fig. 1, in which position it is thereafter automatically retained by the trip-lever 113 bearing against the adjust. ing-screw 112. When the stop-lever is in this position, the fork 11 is shifted so as to, throw the driving-belt (not shown) of the machine onto the fast pulley 9, and thus start the sewing mechanism. The sewing mechanism con-- tinues in .operation until the stitch-wheel 116 moves around half its number of teeth, when the trip-say 117-strikes against the projection 115 of the trip-lever and forces itbackward, so as to disengage the end 113 from the stop-lever screw 112, whereupon the stop-lever is immediatelymoved by the action of the spring 111 and its end 12 brought into engagement with the stop 110 of the pulley 9, so; as to stop the sewing mechanism. The movement of the lever 12- throws the driving-belt 'off the pulley 9 onto the loose pulley 10 and at the same time operates the rod 94 and lever 92 and causes the beveled edge 101 of the tooth 98 to strike against and depress the pin 105 of the spring-bolt 106, thereby releasing the lever 84 and allowing the cam 82 and clutch-piece 74 to move laterally on the shaft 38 and bring the pin 75 into engagement with the hole 76 of the clutch-box, thereby securely locking the two parts 38 38 of the shaft 38 together.

The parts of the mechanism are so arranged relatively with each other that each tooth in the stitch-wheel 116 represents a stitch. There= fore if there are, as shown, eighteen teeth in the wheel eighteen stitches will be made duringa revolution of the stitch-wheel. As there are two trips on the stitch-wheel the sewing mechanism is stopped twice in each revolution of the wheel, so that only nine stitches can be done at a timethat is to say, nine stitches only are made at each tack. This number of stitches has been found to answer very well; but if a smaller or a larger number is desired in each tack in the honeycombing then stitch-wheels with the desired number of teeth can be used to meet the requirements. The stitch-wheels can be easilychanged.

With the completion of the half-revolution of the stitch-wheel the first tack in the fabric has been sewed and the sewing mechanism has been brought to a standstill,the stop-lever being moved into engagement with the stop 110 and the driving-belt shifted onto the loose pulley 10. Immediately the driving-belt is shifted onto the loose pulley, however, the shaft 38 is actuated, and through the closed cluch 74 77 and gearing 36 34 (or 35) the feedscrew 26 is revolved, so as to feed the frame forward. Durin g the revolution of the shaft 38 the groove of the cam 82, (which is shaped for the purpose,) working on the pin 83, moves the lever 84 until eventually it assumes the position shown at Fig. 2 and is caught by the head 108 of the spring-bolt 106. The lever 84 is now locked in position, and the further movement of the cam has, owing to the shape of its groove, the effect of causing both the cam and the clutch 74 to move laterally on the part 38 of the shaft until eventually when a complete revolution of the shaft 38 has been eifected the clutch-pin 75 is drawn right out of the recess 76 of the clutch-box and the clutch mechanism thrown out of gear, whereupon the revolution of the part 38 of the shaft 38 is, along with the movement of the feedscrew 26 and of the frame 14, at once stopped. (Fig. 9 shows the parts of the clutch in gear, while Fig. 9 shows the parts out of gear.) When a complete revolution of the shaft 38 and the feed-screw has been effected, the frame 14 has been moved forward exactly the proper distance for sewing the next tack in the plait. The stop-lever is now again, in the manner before described, thrown out of gear with the stop 110 and the sewing mechanism again started, so as to sew the second tack form a fresh plait in the fabric.

with the required number of stitches. When the stitches have been completed, the sewing mechanism is again stopped by the action of the stitch wheel and the feed mechanism thrown into gear, so as to feed forward the frame the space necessary for the third tack, and so on.

'When the stop-lever is thrown out of engagement with the stop 110, its movement causes the lever 02 to swing backward into the position shown at Fig. 2. In its swing the beveled back part 103 of the tooth strikes against the pin 105, and as a result the tooth (turning on its pivot 104:) yields to an extent sufficient to permit of its point overriding the pin 105.

It is to be noted that the plaited fabric is only sewed through at every second or alternate nick of the locking-strip 18, and the feed-screw is made so that the space between each of its convolutions is equal to the space between the alternate nicks.

When a plait has been sewed in the manner before described, the locking-strip 18 and plaiting-knife 17 are manipulated so as to This second plait is formed by drawing the fabric (shown in dotted lines) up through the slot between the knife and the locking-strip 18 until there is suiflcient material to form another plait adjacent to and parallel with the plait already formed. The operation before described is now performed to form this plait, consisting in moving the knife 17 laterally, allowing the strip 18 to descend and withdrawing the knife to allow the fabric to be held by the clamp. The frame 14 is then by the reversal of the feed-screw traversed backward and the second plait sewed through in the same manner as before, but at the alternate nicksthat is, the nicks missed in the first traverse of the frame. Any number of plaits can be made and sewed in the same manner.

In order to bring about at each traverse of the frame the proper relation between the slide 16 and the nicks of the frame 14 and strip 18, so as to insure that the machine will sew through alternate nicks-that is to say, will sew through the first,third,fifth,&c.,uicks at one traverse and then the second, fourth, sixth, &c., nicks at the next traverse-the frame 14 requires to be moved half the space between two tacking-stitches,and this is done by first disengaging the pawl 137 from its slot (say HO) and then pushing or pulling the frame to the limit allowed by the slots 133 133, so as to bring the other slot 140 below the pawl 137, whereupon the pawl is released by turning the spindle 20 and enters into engagement with the other slot 140, and thereby locks the frame and slide together in the proper position. The pawl 137 requires to be locked in the slot 1&0 at one traverse and in the slot 140 at the next traverse, then in the slot 1&0 again at the third traverse, and so on, the frame being shifted half the step or space between two stitches at each traverse.

The bolt 89 looks the clutch-piece 74 in position.

When necessary, the catch 109 can be moved so as to hold the pin 105 in the depressed position and retain the head 108 of the bolt clear of the lever 84.

In the modification shown at Fig. 19 the frame, instead of being traversed backward and forward under the needle by the feedscrew mechanism, (shown at "Fig. 2,) is arranged so as to be traversed by hand. In this case the slide 16, connected to the frame, has a series of holes 170in it. These holes are spaced at a distance apart from each other equal to the spaces between the alternate nicks of the locking-strip 18. The locking-pin device, consisting of the locking-pin 31, spring 32, thumb-lever 33, &c., is precisely the same as before, with the exception that it is secured to a block 171, fastened rigidly to the slides 15 by means of screws 172. Vith this arrangement the frame is merely pushed forward by hand the desired distance at each step and then locked in position by allowing the pin 31 to enter one of the holes 170 of the slide 16.
